From just bad luck, bad capacitors to a box that is hot to the touch.
450 usually is fine, but there can be a reason if it happens again. Look out for a common issue. Type in BAD MOTHERBOARD CAPACITORS at google.com to get the picture.
Hi, I'm troubleshooting a friend's computer, with Pentium 4 2.4GHz, 256MB RAM, 40GB HDD, 1 CD-RW, 1 CD-ROM. The monitor is not connected to the PSU, but straight to the Mains power supply. The computer is protected by an Automatic Voltage Regulator (so less chance of the damage caused by electrical shocks I suppose). The current PSU's power rating(which has failed) is 450W.
The LED on the motherboard (Asus) lights when the Mains is switched on. But pressing the power button has no effect whatsoever, nothing starts, nothing turns (including the PSU's own fan).
Changing the PSU solves the problem. I've checked, and found nothing physical which I suspect will cause any short circuits.
With the load, 450W should be okay right? Or is this the issue here?
Do you think it's just bad luck that by chance, his PSU is damaged after 3 months, or should I suspect something else is not going well in the computer?
